HD 36187 eller HR 1835, är en ensam stjärna belägen i den mellersta delen av stjärnbilden Duvan. Den har en skenbar magnitud av ca 5,55 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 3 på ca 11,57 mas beräknas den befinna sig på ett avstånd av ca 282 ljusår (ca 86,4 parsec) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet av ca 50 km/s. På dess nuvarande avstånd minskar ljusstyrkan hos HD 36187 med 0,21 magnitud på grund av interstellärt stoft.

Egenskaper

HD 36187 är en vit till blå stjärna i huvudserien av spektralklass A1 V eller A0 V, beroende på källa. Den har en massa av ca 2,3 solmassor, en radie av ca 2,4 solradier och utsänder energi från dess fotosfär motsvarande ca 48 gånger solen, vid en effektiv temperatur av ca 9 500 K. Stjärnan uppskattas vara 311 miljoner år gammal, efter att ha fullbordat 66,9 procent av dess tid i huvudserien. Liksom många heta stjärnor roterar HD 36187 snabbt och har en beräknad rotationshastighet på 145 km/s.
